摘　　要：对20世纪80年代以来有关黄河水下三角洲液化引起的灾害调查实例成果和诱发因素进行了简要汇总,认为该区这些灾害成因之一是液化破坏所致;然后,重点对近期液化破坏的两种研究方法(试验测试和数值计算)及其成果进行了综述,同时,分析了研究中存在的问题;最后探讨今后可进一步研究的内容,建立该区基本土性区域概况,测试波浪作用下土体的液化过程及建立液化引起的灾害发生过程及运移结果预测体系,是今后需要研究的核心内容。Some liquefaction failure examples and their forming mechanisms extracted from survey results at the Yellow River delta since 1980s were briefly summarized and reviewed. It suggests that soil liquefaction is one of the main cause of geohazards in the estuarine area. Achievements of field testing and theoretical studies are also presented in this paper. There are problems remained unsolved. Based upon the findings, suggestions and recommendations are proposed for further consideration, such as, understanding more about the basic regional soil property distribution, testing soil liquefaction process, and establishment of forecasting systems etc.
